2018 Chevrolet Traverse

Incident Description: On 10/2/2024, I discovered a critical failure in the rear suspension of my 2018 Chevrolet Traverse. The rear left control arm had completely rusted through and detached from the vehicle frame. This occurred unexpectedly while my family was backing the vehicle into the driveway from my garage. Had this failure happened while driving, it could have resulted in a catastrophic loss of control, leading to a severe accident with potential for serious injury or fatality to my family and others. This incident raises serious concerns about the safety of 2018 Chevrolet Traverse vehicles. The premature and sudden failure of a critical suspension component due to rust suggests a potential defect in the materials, anti-corrosion treatment, or design of the control arm. This could pose a significant safety risk to all owners of this vehicle model. I have taken detailed photographs of the failed control arm and the affected area of the vehicle frame, clearly showing the extent of the rust and corrosion. General Motors has issued a safety recall (N212346640) for certain vehicles due to a defect in the rear suspension toe links. These vehicles may have received improper electrocoating corrosion protection, making the toe links susceptible to premature rust and fracture. This could lead to a loss of vehicle control and increase the risk of a crash. The similarity of this recall to the failure I experienced with the rear left control arm onmy 2018 Chevrolet Traverse suggests a potential pattern of corrosion-related suspension component failures in General Motors vehicles.   This recall demonstrates that General Motors has acknowledged and addressed similar corrosion-related defects in other vehicles. It supports my concern that the control arm failure on my Traverse may also stem from a manufacturing defect and warrants a thorough investigation by the NHTSA.

I purchased these Carseats after I was in an accident and needed to replace the 2 that I had, The tethers attached to the carseat were not effective at all, I could not get them anywhere near close to actually securing the Carseats. So I opted to use my vehicles seatbelts, with the seatbelts pulled as far as I could get them and locked the Carseats still moved more than an inch. I had to have my husband help me push the carseat as far down into my seat that I could to get the least amount of movement as possible. One of the Carseats even tipped over while I was driving after all of this. Needless to say that I will be replacing these seats as I do not feel they would keep my children safe in the event of an accident, I feel as though these seats endanger my children because they aren't keeping them secure enough not to become projectiles in the event of an accident.

bracket on the exhaust flex pipe bracket broke. This is a known issue by GM (PIP5681C) that covers 2018-2022 Chevy Traverse and Special Coverage notices have been issued for at least the 2019 (N212356540) and 2021 (N222385510). I called GM today and they said my 2018 Traverse would not be covered even though it is a known issue and had a bulletin issued on it. If this is a known issue for several years (including 2018), why wouldn't the 2018 model be included and covered?

While I was driving, the rear sunroof suddenly "exploded". I was shocked as I did not feel any impact, but it sounded like a wrecking ball had hit my car. I don't think I swerved into the other lane or anything like that, but honestly it happened so fast, I'm not sure. My heart was racing, and I felt like I was in danger, but able to pull over fairly soon after. I began to feel unwell as if my blood pressure was elevated, which I'm sure it was. I inspected the outside of the vehicle and didn't see any damage, but then from inside noticed a crackling sound, which was localized to the rear sunroof. I examined it from the top and found it to be cracking in various areas around the perimeter of the glass. The shade on the sunroof was closed, so I don't believe any glass entered the interior of the car. I called my daughter to tell her what had happened and drove the rest of the way home. At this point, I have not had anyone else look at it but am reaching out to the dealership where I bought the car.
